Interorbital Systems successfully test fired the Sea Star’s Stage 3 Rocket engine.
The engine’s sound was recorded by a hollywood audio crew for use in the upcoming science fiction feature film “Serenity” which is based on the TV Series “FireFly”. The Film is slated for release next fall.

The engine performed according to design (with a 40-second burn), generating 3.000 pounds of thrust with an equivalent vacuum specific impulse of 299 seconds. It was fired twice on the same day.
During the course of the test, the engine was throttled up and down several times.
It was successfully throttled down to as low as 20% of maximum without any measurable loss in performance.
